This invention relates to new and useful improvements in means forattachment to the valves ofv gas stoves whereby the same may be securelylocked in open or closed position or at any point therebetween toprevent the accidental turning of the valve, or

part of small children.

-An important object of the invention is to provide a device of thischaracter thatgis readily attachable to valveson conventional types ofgas stoves without in any manner whatever altering. the structure of thevalve,

nor of the directly, associated parts of'the stove, or without requiringany unusual V skill.

that is highly Well I purposes intended.

A still further and important object is to provide alocking attachmentof this character that is extremely simple-of construction, inexpensiveofmanufacture, and-one adapted for all the Vi ith the foregoing andother objects in view as the nature of the inventionfwill :be

" 5 better understood, the same comprises a novel form, combination andarrangement of parts hereinafter more fully described, shown 111} theaccompanying drawing and claimed. In the drawing wherein like referencecharacters indicate corresponding parts throughout the several views:

' Figure 1 is a side elevation of one of the control valves of aconventional gas stove disposed beneath the gas distributing pipe and aparticular burner, said valve being equipped with my improved means forfacilitating the locking of thevalve.

This typeof valve includes the usual vertically projectingstem 7 upon the upper endof which is disposed a handle 8 forfacilitating the proper and easy turning of the stem to move the valveto open or closed position. r

and partly in vertical cross section of said unit,

ln'carrying out nyinvention I, provide a two-plate clamp; designatedgenerally by the reference character 9,the same consistmg of a pair ofclamp plates 10 and ll that are adapted, for disposition over the upperend of the valve stem 7 as well as the headed connection between said 8.The four corners of;

The invention further consists of a unit constructed'for rigidattachment to thebody generally by the reference character 16, de-

The lower end of the plate 21 is formed also with an opening forregistry with an opening in the adjacent end of the forwardly extendingpin 20 of the arm 19 so that the plate 21 may be secured to saidpin andto said bosses 22 by set screws 23.

It will furthermore be readily-understood that when it is desired tolock the control fully openor closedullopenor closed position, it willjonly be to thread the elongated screw 15 thereof within'the properopening 18 of the semi-circularplate 17. a a s V In viewlof theforegoingdescription when consideredin conjunction with the accom and efficientdevice for ready association with the valves I be positively lockedeither when'fully opened or closed, or at any intermediate position'andthat is otherwise well adapted for all the purposes heretoforedesignated, i I
